Objective The aim of this study was to evaluate whether PRDM16 gene polymorphisms were associated with dyslipidemia. Methods The polymorphisms of rs2651899, rs2236518, rs870171, and rs2282198 in PRDM16 gene in 528 participants were genotyped by the method of snapshot or ligase detection reaction. The genotype differences and the allele differences between the case group and the control group were analyzed. Linkage disequilibrium analysis was performed with SHE-sis online software. The interaction between rs2651899, rs2236518, rs870171, rs2282198 and gender, age, BMI were analyzed by MDR software. Results The frequency of allele A in rs2651899 locus was significantly higher in low HDL-C group compared with that in control group[OR(95%CI)=1.32(1.02-1.71), P=0.033]. The frequency of A/C genotype in rs870171 was significantly different between LDL-C abnormal group and control group[OR(95% CI)=1.97(1.01-3.86), P=0.037]. There may be interaction between rs2236518 and sex, which is a risk factor for low HDL-C[Model Ⅱ: OR(95% CI)=1.958(1.366-2.809), P<0.01]. There may be interactions among rs2651899, rs2236518, rs870171, and rs2282198, which seemed to be risk factors for lower HDL-C[Model Ⅳ: OR(95% CI)=3.991(2.707-5.884), P<0.01]. rs870171, rs2282198 may have interaction with age, which is a risk factor for high LDL-C [Model Ⅶ: OR(95%CI)=3.991(2.707-5.884), P<0.01]. Conclusion Allele A of rs2651899 may be a risk factor to low HDL-C. Under the codominant inheritance patterns, genotype A/C of rs870171 may be a risk factor to high LDL-C. In addition, there may be interaction between SNPs with gender and age.

Objective:
To investigate the influence of occupational aluminum exposure on cognitive function and glutamate receptor protein expression in peripheral blood lymphocytes in workers and the possibility of glutamate receptor being used as a biomarker for cognitive impairment in aluminum workers.
Methods:
From October to December, 2014, cluster sampling was performed to select 121 workers in aluminum electrolysis workshop as exposure group and 231 workers in thermoelectric workshop and logistics department as control group. Mini-Mental State Examination, clock drawing test, digit span test (DST) , verbal fluency test (VFT) , and Fuld Object-Memory (FOM) Evaluation were used to analyze cognitive function. Graphite furnace atomic absorption spectrophotometry was used to measure plasma aluminum level as an exposure indicator. Enzyme-linked immunosorbent assay was used to measure the content of glutamate receptor proteins in peripheral blood lymphocytes, including the subunits of N-methyl-D-aspartate receptor NR1, NR2A, and NR2B and metabotropic glutamate receptor 1 (mGluR1) . The correlation between cognitive function indices and the content of glutamate receptor proteins was analyzed.
Results:
There was no significant difference in plasma aluminum level between the control group and the exposure group (132.52±80.40 μg/L

Objective:To evaluate the effect of experiential health education on patients discharged from hospital with the tube after pancreaticoduodenectomy.Methods:A total of 65 patients admitted to the General Surgery Department of Peking University Third Hospital for pancreaticoduodenectomy from September 2020 to August 2021 were selected as the study objects by convenience sampling method. The 31 patients with pancreaticoduodenectomy who received routine education about drainage tube from September 2020 to February 2021 were selected as the control group, and 34 patients with pancreaticoduodenectomy who received experiential health education about drainage tube from March 2021 to August 2021 were selected as the study group. The self-nursing ability and self-management of drainage tube of the patients in both groups were observed.Results:The total score of drainage tube self-care ability, drainage bag fixation score, drainage bag replacement score, drainage fluid dumping score, anti-drainage tube pull score, drainage tube extrusion method score were 10.00(10.00, 10.00), 2.00(2.00, 2.00), 2.00(2.00, 2.00), 2.00(2.00, 2.00), 2.00(2.00, 2.00), 2.00(2.00, 2.00) points, Higher than the control group 5.00(4.00, 5.00), 1.00 (1.00, 1.00) and 1.00 (0.00, 1.00), 1.00 (1.00, 1.00) and 1.00 (1.00, 2.00), 1.00 (1.00, 1.00) points, the differences were statistically significant ( Z values were -7.31--5.78, all P<0.05).In the self-management of drainage tubes in the study group, the drainage tube pulling rate, the incidence of exudation around drainage tubes, and the rate of leakage of drainage fluid registration were 8.82% (3/34), 14.7% (5/34), and 5.88% (2/34), respectively, lower than 61.29% (19/31), 41.94% (13/31), and 87.10% (27/31) in the control group, with statistically significant differences ( χ2=19.94, 6.00, 43.28, all P<0.05). Conclusions:Experiential health education can effectively improve drainage tube self-care ability of patients after pancreaticoduodenectomy, promoting postoperative rehabilitation of patients.

Objective To investigate the role and mechanism of SR8278,a synthetic antagonist of nuclear receptor subfamily 1 group D member 1(NR1D1),in alleviating the structural and functional impairment of the extraorbital lacrimal glands induced by jet lag in mice.Methods Totally 36 healthy wild C57BL/6J mice aged 8-10 weeks were randomly divid-ed into 3 groups(normal group,jet-lag group,and jet-lag+SR8278 group)after adapting to a circadian rhythm chamber under the 12 h light/12 h dark(12 h/12 h LD)cycle for 2 weeks,with 12 mice in each group.Mice in the normal group were fed in a circadian rhythm chamber in a 12 h LD cycle,mice in the jet-lag group were fed in a 12 h/12 h LD cycle with an 8-hour advanced LD schedule,and mice in the jet lag+SR8278 group were fed in a 12 h/12 h LD cycle with an 8-hour advanced LD schedule and received 25 mg·kg-1 SR8278.At the end of 5 days of intervention,locomotor activity,core body temperature and tear secretion of mice in each group were collected,and the weight of lacrimal gland tissues and size of lacrimal gland cells were measured.Immunohistochemical methods were used for histological evaluation of the extraor-bital lacrimal glands in mice.Lacrimal ribonucleic acid(RNA)was extracted for high-throughput RNA-sequencing analysis containing NR1D1,and the obtained transcriptomic data were used for KEGG and GO functional enrichment analysis.Re-sults Compared with the normal group,the jet-lag group had higher daytime activity,lower nighttime activity,higher daytime core body temperature,and lower nighttime core body temperature,with statistically significant differences(all P<0.05).Compared with the jet-lag group,the jet-lag+SR8278 group had lower daytime activity,higher nighttime activi-ty,lower daytime core body temperature,and higher nighttime core body temperature,with statistically significant differ-ences(all P<0.05).Compared with the normal group,the jet-lag group showed a decrease in lacrimal gland weight and tear secretion and an increase in size of lacrimal gland cells,with statistical significance(all P<0.05);compared with the jet-lag group,the jet-lag+SR8278 group had an increase in lacrimal gland weight and tear secretion and a decrease in size of lacrimal gland cells,with statistical significance(all P<0.05).Compared with the normal group,the jet-lag group showed a higher expression of NR1D1 in the lacrimal gland at night;compared with the jet-lag group,the jet-lag+SR8278 group showed a lower expression of NR1 D1 in the lacrimal gland at night(both P<0.05).Bioinformatics analysis showed 947 significantly different genes in the jet-lag group and the jet-lag+SR8278 group,of which 43 are significantly upregulated genes,and 904 are significantly downregulated genes.The Notch signaling pathway has the most significant difference.Conclusion SR8278 effectively enhances the tear secretion function of jet-lagged mice by targeting NR1D1 inhibition.This process may be completed through the Notch signaling pathway.
